At Larry H. Miller Chrysler Dodge Jeep Ram 104th in Denver, CO, we frequently diagnose common check engine codes on the 2022 Jeep Cherokee such as P0420 (catalyst inefficiency), P0171 (system too lean), P0300 (random/multiple cylinder misfire), P0455 (evaporative leak), and P0135 (oxygen sensor heater). Left unaddressed, each code carries escalating costs: a failed O2 sensor can reduce fuel economy and lead to poor drivability; untreated lean conditions can damage pistons and catalytic converters; misfires can ruin ignition coils and catalytic components. Catalyst replacement can cost well over $1,000 when left to fail, while early sensor or ignition repairs are typically far less expensive and restore fuel economy and emissions compliance. Our certified technicians use OEM diagnostic tools and genuine parts to provide precise repair plans and transparent pricing, helping you avoid repeated visits and higher lifetime repair bills.
